An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for medical care and were later released.
Police detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
